titles are not tag :))

Thank you MR anvari

omG Tnx AA :D

This should also help.

thanks for the link. It was helpful.

another segment tree & bits

Segment tree on string: Letter Array

Hackerrank's advanced level problems on segment trees are nice too. Check them out.

I was looking for this everywhere , i think it will be great helpful for me Thank you.

How come i can only see problem names in russian?

Umm... right now it can't be seen in english, which I believe most of us need, it would be great to show it like this: [problem code] [english name] / [russian name]

Now you can see problems in English :))

Again they are in russian; Why ?

UPDYou fixed that again, but in my comment it is russian yet,how to fix it?Is 356A — Knight Tournament a segment tree problem?

A little bit late ;-) Yes, it is possible to solve it with a segment tree. But instead of updating a single value and querying for ranges, you have to invert it so that you can modify an interval and get access to each element. Additionally you have to make sure that you insert the fights in the reversed order, otherwise some fights will overwrite others. Here is my implementation: 23198751

Thank you :)

This should be updated with the problem links in this post. How can it be done ??

Segment Tree & Dp: 629D - Babaei and Birthday Cake

Segment Tree & Heavy Light Decomposition : 117E - Tree or not Tree

Wow! This will be so much helpful to many. Thanks for the effort!

Titles of the problems appear in Russian in this blog post. Is it possible to change to English? (I remember it was in English previously. Maybe some settings changed for me.)

760E is also a segment tree problem

This question(570C) can also be solved using segment tree.Here is my solution.

That's overkill. There exists an easier and faster solution for that problem.

Segment tree + dp 675E - Trains and Statistic

You can also find many Segment Tree problems on A2 Online Judge. They are ranked by their difficulty, and also including many online judges like codeforces, SPOJ, codechef etc.

Segment tree + DP problem : D. Babaei and Birthday Cake

Can anyone help me with this? I don't know how use a segment tree in order to solve the problem. I solved this using a C++ set. Thanks in advance.

How to solve 459D using a segment tree? I solved it using Fenwick tree but I could not think of a solution using segment tree.

This blog contains 20 Segment tree Problems (Easy, Medium, hard) along with there solutions. Hope it helps someone.
